if your talking about that big bulky ring that is near it, i'd leave it in there. it keeps the cords from accidently slipping into the p/s and causing some potentially fatal damage to the p/s. work with the 'slug', not against it.

If it is anything like the older PowerMac models, it is a black ring around the cord that keeps it from touching whatever is near it; in this case, the power supply. I would imagine that it is put there for heat purposes.

My suggestion is to leave it alone; work around it. It was there for a reason. No sense potentially destroying a machine if you can work around it.

My Powerbook's powersupply frayed (near the top, light thingy) i had to rip the whole stupid thing open, then jimi rip it. The black thing is a heat shild, it wont hurt anything to remove it, but it is there to stop shock from comming to your comp. You can move it if you wanted and then it will still serve its orignal purpouses. but so far after moving the one on my comp, no problems have come to it... good luck tho.
